Cinq App

Stop texting back and forth trying to find a time. Cinq lets you create events and availability polls right inside iMessage — no app download needed for your friends. Create: Pick your dates, choose a time window, and send a beautifully styled invite directly into your group chat. Choose from three cover themes (Terminal, Blueprint, Data Card) with multiple color options, or upload your own image. Invite & Polling: Fixed invites for when you already know the date and just need RSVPs. Availability polls for when the group needs to find the best time — everyone marks their slots, and Cinq surfaces the top options. Accessible: Your friends don't need to install anything. Toggle on "Include web link" and anyone without the extension can participate through a browser link sent right in the chat. Smart Availability: Tap or drag to mark when you're free. See how many people overlap on each slot with clean count badges. Two-level selection — mark times as "available" or "preferred" so the host can pick the best fit. Google Calendar Integration: Connect your Google account to see your busy times overlaid on the grid. When a time is confirmed, it lands on your calendar automatically. Privacy-first: Phone verification only — no marketing texts, ever. Guest participants don't need an account. Your data stays yours.
